To enable HA, you must first make sure all Virtual Machine Servers in the server pool:

Use the same shared storage.

Are in the same OCFS2 or NFS cluster.

Are Oracle VM Server Release 2.1.2 or above.

Have the same cluster root, which is a specially designated shared storage used for heatbeating in the cluster. For example, the cluster root might be example.com:/OVS for an NFS cluster, or /dev/sdd6 for an OCFS2 cluster. The heartbeat file would be located at example.com:/OVS/.server_pool_hb for an NFS cluster. There is no heartbeat file for an OCFS2 cluster as one is in-built in the file system.

Have the cluster root mounted at /OVS. All other storage may be mounted at the standard location of /OVS/uuid.

Have moved any /OVS mount points (set in FSTAB for Releases 2.1 or 2.1.1) to the /etc/ovs/repositories file. All storage, even that mounted at /OVS, must be maintained in the /etc/ovs/repositories file. You can move the mount points to the /etc/ovs/repositories file with the following command:

# /usr/lib/ovs/ovs-cluster-check --alter-fstab

Have a shared cluster root at /OVS, and not local, using clustered OCFS2 on SAN, or ISCSI storage, or NFS on NAS. The default local storage is OCFS2, and is not supported with HA.

Question #3
A low priority guest is using up more of the physical network traffic than desired. Select the two valid network QoS settings for restricting outbound network traffic?
  1. A
    [max_rate=lMb/s]
  2. B
    [rate=lMb/s@20ms]
  3. C
    [rate=250Kb/s]
  4. D
    [max_rate=unlimited]
  5. E
    [rate=250Rb/s, max rate=1Mb/s]

Correct Answer:
BC

Question #4

  1. A
    Avoid installing additional software in dom0.
  2. B

  3. C
    Install virus checking software in dom0.
  4. D
    Use Trusted Computing Modules for Xen0.
  5. E
    Do not share physical network cards between hosts that are on a different subnet.

Correct Answer:
AE

Question #5
Networking is not working for several guests on a particular host. Which two commands can help troubleshoot the networking?
  1. A
    xm list -1 will show all of the network interfaces for all of the virtual machines, which can be used to see which bridge is having problems.
  2. B
    config_network.py -l will show which network interfaces are in use, and which are having problems.
  3. C
    brctl show will show the status of each bridge, and which VIFs are connected to it. This canthen be used to determine which bridge is having problems.
  4. D
    System-config-network will list the virtual interfaces, which can be inspected to see which are having problems.
  5. E
    ifconfig -a will show a list of all network interfaces and their current status, which will help determine which bridge is having problems.

Correct Answer:
CE
